tape data conversion
Converting Backup Tapes from Legacy System
A major bank had decided to rationalise and upgrade their backup system.  Previously they had been using a managed service, whereby all the data was backed up on DLT tape.  Over the years they had accumulated 150 terabytes of data of incremental and full backups on DLT tape. 
The client planned to operate a backup server using virtualisation technology.  The new backup application proposed was Symantec NetBackup. Only a fraction of there existing backup tapes were live data and much of it was duplicated or legacy information.  Firstly we catalogued every tape to provide a file listing of all the data. To give you an idea of the scale, we ran ten tapes in parallel.  A full read of each tape took four hours - so that is ten tapes every four hours. From this we got a file listing for each tape, which was subsequently managed, by de-duplicating data and teasing out each thread for individual servers.  
From the file listing the client choose the most recent data set, representing 20 terabytes of data.  This was restored to the new server.  Everything else was then archived in its existing format.  We provided the hardware and software for this archive.

"Thank you so much for all your help - Data Recovery Specialists are a real life saver!  I do not know what I would have done without the data you recovered.  We would have probably had to re-record all the location shots, which would have been time consuming and very expensive"  BBC Wales
